Definitions

  • This invention relates to the improvement of comestibles.
  • comestibles are improved through the addition thereto or the incorporation therein of parenchymal cell cellulose (PCC) in amounts sufficient to effect such improvement.
  • PCC parenchymal cell cellulose
  • This invention is also directed to methods for the improvement of comestibles through the inclusion of parenchymal cell cellulose.
  • the invention is also directed to methods for the preparation of drugs and cosmetics through the incorporation of parenchymal cell cellulose therein and also to the drugs and cosmetics thus prepared.
  • foods, drugs and cosmetics which, for the purposes of this specification are included in the term "comestible" are improved by having their physical and physicochemical properties improved through the addition of PCC.
  • comestibles including foods, drugs and cosmetics, having improved cost factors, improved physical processing capabilities, lower cholesterol level, lower caloric level, and other beneficial properties.
  • Texture provides a major distinguishing feature for most foods. Texture is an important parameter that controls the desirability of food. A good steak is characterized by a suitable "yield” upon biting into it. Most puddings are similarly characterized by a proper "yield” but of a different strength. For those beverages that are relatively thick or more viscous it is desirable that they be shear thin­ning, i.e., that the viscosity becomes lower in the throat during swallowing than is experienced at the lower shear rates in the mouth. Viscous beverages that are not shear thinning are either slimy, Szczesniak and Farkas, J. Food Sci. 27 , 381 (1962), or quickly satisfy.
  • Ice cream and butter textures are partly derived from the melting of the ice crystals and butter fat, respectively; these represent other types of mouthfeel properties - for example, the cooling from the ice melting or the coating of the mouth by the butterfat.
  • thinner or thicker textures are achieved by increasing the solids content, or by maxi­mizing attractive forces between individual components so that a structure is developed, i.e., some sort of gelation. This latter is achieved through changes in pH, salt levels, or the addition of certain other components.
  • Thicker mayonnaise may be achieved with high levels of emulsified oil particles or by the addition of carbohydrates that partly cross-link to form a partial gel. Xanthan gum is commonly used for this sort of crosslinking.
  • xanthan gum is dramatic in its behavior because not only does it give a solubilized network, but it also forms colloidal aggregates whose breakup under shear contributes to yield point and to shear thinning - for example, see Pettitt, Polysaccarides in Foods , Butterworths, 1979; Sanderson, Prog. Fd. Nutr. Sci. , 6 , pp. 77-87 (1982).
  • Salad dressings are thickened with higher levels of herbs and other solids, by the addition of carbohydrates (again usually xanthan gum), or by adding materials that increase attraction between components. The latter are often surface active materials such as propylene glycol alginate.
  • Microcrystalline cellulose such as the commercially available Avicel® materials, has become recognized as a "Gold Standard" for this function. While it is very finely divided, its chief functionality results from the needle shape of the crystal and the ability of these crystals to interact with each other to set up a structure. Thus, a yieldpoint is demonstrated at relatively low levels and shear thinning is a charac­teristic feature, McGinley et al, Gums and Stabilizers for the Food Industry , 2 , Pergamon (1984).
  • the measurable parameters of texture are rheological in nature.
  • viscosity resistance to flow, i.e., resistance to irrecoverable deformation
  • elasticity resistance to recoverable deformation
  • rheological measurements provide in many cases an indication of the physical stability of a food. The latter is especially important for those foods that are composed of two or more immiscible phases.
  • An emulsion such as mayonnaise is one such system.
  • Oil is dispersed into very small droplets as a disperse phase and the interstitial spaces are filled with aqueous continuous phase.
  • Creaming, flocculation or coagula­tion, and coalescence are the three principal mechanisms of destabilization that must be minimized for any food emulsion product of technological importance.
  • the measured stress values are higher than that which would be observed from simple viscous flow in the absence of structure.
  • shear rate is increased still further, progressively greater proportions of structure are destroyed and the length of time required for reversal is greater than allowed by the shear rate.
  • the stress is observed to decrease with the increased shear rate and at some high shear rate, all structure may be obliterated.
  • the observed stress that results from only viscosity is measurable.
  • These very high shear rates are often technologically unimportant.
  • the yield and the degree of shear thinning are directly relevant to the rates of shear experienced during mastication, pouring, whipping, spreading, etc. and therefore an apparent viscosity at a particular shear rate is useful.
  • the power law plastic [log (corrected stress) vs log (shear rate)] is then used to estimate the degree of shear thinning via the "flow behavior index" where values of 1 indicate Newtonian behavior and values of less than 1 indicate shear thinning.
  • the apparent viscosity is determined at a shear rate of 1 sec ⁇ 1 (consistency coefficient).
  • corrected stress is the measured stress minus the yield value.
  • Shear thinning is usually desirable in foods to facilitate mastication, swallowing, and processing, and to avoid sliminess.
  • MMC microcrystalline cellulose
  • Avicel® a colloidal sized elongated crystal provides structure that appears not to involve molecular entanglement, but rather a "house of cards” structure.
  • colloidal forces maintain the crystals in a certain formation with respect to each other and with respect to other components of the food matrix.
  • Another form of stabilization is retardation of ice crystal growth in the frozen state as a result of high viscosity and/or physical barrier. Growth of ice crystals results in loss of smoothness and damage through freeze dehydration. Hydrocolloids (gums) are used in foods for texture improvement via viscosity, yield stress and shear thinning modification, stability via emulsification and structure, and flavor release via shear thinning.
  • parenchymal cell cellulose to foodstuffs, drugs, cosmetics, and other comestibles, can improve the physical, physicochemical and stability properties of such materials. It has also been found possible to provide methods for the preparation of foods, drugs and cosmetics through the incorporation of parenchymal cell cellulose (PCC) therein, to result in unique compositions having improved properties. Thus, it has been found possible to prepare a stabilized dispersion of a first material and a second material comprising an amount sufficient to stabilize the dispersion of parenchymal cell cellulose.
  • PCC parenchymal cell cellulose
  • Such dispersions may comprise liquid-in-liquid emulsions, oil-in-water emulsions, water-in-oil emulsions, foams of gas and liquid, emulsions or suspensions of solid and liquid, dispersions of gas with a plurality of liquids, and other multi-phase systems.
  • Such materials find particular utility in the food, drug and cosmetic industries as well as in other industries dealing with comestibles.
  • Parenchymal cell cellulose used in accordance with the invention can provide a source of non-nutritive or dietary fiber for use in comestibles. It can also improve the viscosity, stabilization, and texture of foods, drugs and cosmetics and comestibles in general.
  • the invention can also provide foodstuffs having lower levels of fat, cholesterol or other fatty substances while retaining acceptable physical and physicochemical properties appropriate to the food.
  • the invention can provide foodstuffs having overall lower caloric value while retaining good physical and physicochemical properties, good taste, and suitable processability.
  • comestibles comprising parenchymal cell cellulose.
  • Parenchymal cell cellulose as herein defined, has been found to be extraordinarily useful in a number of aspects of comestible production.
  • PCC is highly utilitarian for a wide variety of rheological uses and improvements.
  • Such comestibles may be prepared in the form of emulsions, dispersions, foams, gels, doughs, and other forms.
  • dispersion is defined generically to include emulsions, foams and the like.
  • Comestibles in accordance with the present invention may be prepared comprising yolk-containing aqueous emulsions, frozen confections, ice creams, ice milks, frozen toppings, mayonnaises, mayonnaise substitutes, thixotropic condiments, sauces, and a wide variety of other materials.
  • Such comestibles may also be prepared comprising lotions, creams, jellies, salves, mousses, whips, and a whole host of dispersions, emulsions, gels, foams, and other materials useful in the food, drug and cosmetic industries.
  • the present invention also provides reconstitutable mixes for pre­paration of any of the foregoing materials.
  • a particular, preferred embodiment of the present invention provides comestibles in the form of foams such as albuminous foams, proteinaceous foams, frozen foams, whipped toppings, and a whole host of reconstitutable mixes for such materials and replace­ments and substitutes therefore.
  • parenchymal cell cellulose may be incorporated into batters, doughs, mixes and the like in order to improve texture, processability, or other rheological properties.
  • Another preferred embodiment secures improvements in beverages and the like through the addition of PCC thereto. Juices, dairy and nondairy frozen beverages, concentrates and the like can all benefit.
  • methods for altering a physical or processing property of a comestible comprising an addition to the comestible of an amount sufficient for effecting the alteration by parenchymal cell cellulose.
  • the amount of parenchymal cell cellulose added to the material to effect the alteration is between about 0.01 and about 30% by weight. It is still more preferred to add from about 0.1 to about 5% by weight.
  • Dietetic or other specialty comestibles may also be prepared in accordance with this invention in view of the fact that parenchymal cell cellulose has a negligible food value and is devoid of fat or cholesterol.
  • methods for preparing comestibles having reduced caloric content while maintaining commercially acceptable physical and processing characteristics comprising formulating the comestible to include, for example, at least about 0.2% by weight of parenchymal cell cellulose.
  • Similar improvements in the preparation of comestibles to provide such comestibles having reduced lipoprotein or fat levels while maintaining commercially acceptable physical and processing characteristics are also included within the invention.
  • such comestibles are preferably formulated to include at least about 0.2% by weight of parenchymal cell cellulose.
  • parenchymal cell cellulose may be co-isolated with certain hemicellulosic components of the materials from which the PCC is derived.
  • sugar beet pulp, citrus pulp or other parenchymal cell containing material may be treated in such a way as to co-isolate both parenchymal cell cellulose and certain hemicellulosic components of those plant materials.
  • the resulting, combined materials may be useful for any of the methods and in any of the materials discussed above under appropriate circumstances.
  • the hemicellulosic components of such blends, mixtures or co-isolates form a natural gum having properties not unlike naturally-­occurring gums well known to persons of ordinary skill in the food science art. Accordingly, the inclusion of the hemicellulosic components may find beneficial use in one or more embodiments of the present invention.
  • parenchymal cells especially parenchymal cells found in sugar beets and citrus, possess unique morphologies.
  • a method for the isolation of such cells from non-parenchymal cellulosic and other structures of sugar beet pulp or other parenchymal cell sources has been discovered and is disclosed in U.S. Serial Number 512,940 filed July 12, 1983, incorporated herein by reference or in EPO Patent 102,829, incorporated herein by reference.
  • dispersions and suspensions of such cellulosic components of parenchymal cells have been made and have been found to possess unique rheological, chemical and physical behaviors and properties useful for the practice of certain embodiments of this invention.
  • Cellulose is known to comprise a linear array of Beta 1-4 D-glucopyranose units. With regard to this primary form, all celluloses are the same. Thus, starch and dextran, which are also glucose homopolymers, differ at this level of analysis.
  • the arrangements of chains of Beta 1-4 D-glucose to form an ensemble comprises secondary structure of cellulose.
  • the ensemble is designated the microfibril.
  • the chains within the ensemble may be arrayed in parallel, anti-parallel, or complex structures; they could also be arranged in a random fashion.
  • elementary cellulose types have been recognized by those skilled in the art.
  • Representative of the structure observed at this level are cellulose I, II, III, and IV which comprise the known forms of crystalline cellulose.
  • Low order chain arrangement which may be more or less random depending on the pedigree of the cellulose, comprises amorphous cellulose.
  • Native forms of cellulose contain type I structured regions while reconstituted celluloses such as rayon are largely type II.
  • the dimensions of native, individual microfibrils are largely a function of the number of parallel chains generated by the biosynthetic organelle characteristic of the specific cell or tissue being assembled.
  • the microfibril comprising the secondary structure of cellulose may in turn be arranged to form a tertiary structure.
  • regions of varying crystallinity may be dispersed inter se or among areas of amorphous cellulose in adjacent microfibrils to form strong intermicrofibril associations which stabilize varying tertiary structures.
  • structures such as fibrils, bundles, sheets, and the like may be seen to comprise tertiary structures.
  • the cell wall of a parenchymal cell is best described as a tertiary structure.
  • such a parenchymal cell wall of a sugar beet is easily distinguished from, for example, a stalk fibril or fiber which may also be found in sugar beets.
  • the quaternary structure of a cellulosic material is best understood as being an arrangement or combination of tertiary structures.
  • the plant vascular bundle known as phloem may be distinguished from a similar vascular bundle, xylem, as having a different quaternary structure even though the tertiary structures may be similar or even identical.
  • parenchymal cell walls may be constructed somewhat differently to form the parenchymal cells of, for example, sugar beets or certain fruits.
  • Quaternary structure may also be envisioned as comprising macroscopic assemblages characteristic of specific plant tissues. Such structures will, of course, comprise non-cellulosic materials as well.
  • parenchymal cell cellulose such as those found in sugar beets and other pulpy plant tissue
  • PCC parenchymal cell cellulose
  • dispersions of such parenchymal cell cellulose especially in aqueous media, have other useful physical and rheological properties as well. It is believed that isolation of parenchymal cell cellulose has not heretofore been accomplished and that such cellulose and cellulosic dispersions have not heretofore been known.
  • PCC The physicochemical and functional uniqueness of PCC is thought to be related to its secondary and tertiary structure.
  • Primary structure the way in which the D-glucose molecules are combined to form a linear polymer, is the same for all cellulose.
  • the primary structure chains have high affinity for each other and spontaneously selfassociate to form amorphous or other levels of structure which reflect their ordered grouping and spatial arrangement with respect to each other. It is here that PCC begins to significantly differ from most other forms of cellulose.
  • the assembly of the microfibril is controlled by the biosynthetic organelle(s) to be characteristic of the physiological obligations of the cell being formed. Low angle x-ray crystallography now indicates that the PCC is composed of ordered regions of very small dimension with few reflecting planes.
  • PCC shape associated with secondary structural elements of PCC now appears from high resolution, transmission electron microscopy to be a microfibril structure of extremely small dimensional order.
  • membrane morphology of PCC reflects a tertiary structure resulting from intermeshed layers of microfibrils.
  • Parenchymal cell cellulose is prepared primarily from structural manipulation at the quaternary and tertiary level although some effect on lower levels of structure would be expected.
  • production of other highly functional celluloses such as micro­fibrillated cellulose and microcrystalline cellulose from high purity alpha cellulose wood pulps primarily reflects structural manipulation at the tertiary and secondary levels, respectively. Thus, each is distinguished from PCC.
  • PCC can be isolated from the acid hydrolysis of sugar beet pulp at pH's below about 4.5 and preferably at pH's below about 4.0 and even more preferable between 4.0 and 2.0. This condition of strong acidity is maintained at a temperature above room temperature and for a period of time which is sufficient substantially to liberate pectin and arabinogalactan from the sugar beet pulp.
  • a temperature greater than about 125°C be employed. It is more preferred to employ temperatures from about 125°C to about 250°C and even more preferred to employ temperatures between about 140°C and about 200°C. Still other preferred embodiments employ temperatures between about 150°C and 180°C.
  • reaction times which are sufficient to liberate hemicellulosic components from parenchymous tissue, pectins and arabinogalactans will vary depending on the pH employed and the reaction temperature. It is preferred that reaction times less than about 600 seconds be employed. It is still more preferred that reaction times less than about 360 seconds be so employed with a still more preferred range being reaction times below about 200 seconds. In general, reaction times effective to liberate the components will be greater than about 15 seconds and preferably greater than about 30 seconds. According to one preferred method for the isolation of PCC, sugar beet pulp in aqueous slurry is acidified to a pH of about 2.5 with concentrated hydrochloric acid and hydrolyzed for approximately 120 seconds at 160°C.
  • unlimed citrus pulp was acidified to a pH of about 2.2 with HCl and hydro­lyzed for about 170 seconds at about 165°C.
  • pH 2.2
  • hydro­lyzed for about 170 seconds at about 165°C.
  • wide combination of pH's, reaction time and temperature will be satisfactory for obtaining PCC.
  • reaction conditions for preparing PCC by what they accomplish rather than by their numerical values.
  • substantial degradation refers to degradation in excess of approximately 25% of the total mass of either pectin or arabinogalactan component.
  • it is preferred that such degradation be minimized.
  • a certain degree of degradation may be allowed or even encouraged such as when coproduction of novel vegetable gums with PCC is desired.
  • the isolation of PCC from sugar beet pulp or other parenchymal cell-containing plant material may also be accomplished in strongly alkaline conditions.
  • combinations of high (strongly basic) pH, relatively high temperature and relatively short reaction times may be so employed for such isolation.
  • This combination of strongly alkaline pH at high temperatures for short times can allow the coproduction of hemicellulosic components from such plant materials without substantial degradation if such is desired.
  • the co-isolation of PCC with hemicelluloses may be desired.
  • pH's greater than about 8.0 be employed for this hydrolysis. It is still more preferred to employ pH's between about 9.0 and about 13 and even more preferred to employ pH's from about 10.5 to about 12.
  • temperatures between about 125°C and 250°C may be employed. It is preferred that temperatures between 140°C and about 200°C be employed while still more preferred are temperatures between about 150°C and 180°C.
  • Reaction times less than about 600 seconds are preferred with reaction times less than about 200 seconds being more preferred and reaction times from about 30 to about 200 seconds are still more preferred for certain embodiments. In general, reaction times greater than about 15 seconds are needed.
  • a tubular reactor which passes a slurry of parenchymal cell containing material at elevated temperature and pressure and at the desired pH through its length to one or more exit orifices.
  • the slurry is then sprayed or "shot" through the orifice into a region of lesser pressure.
  • shearing may also be employed after isolation of parenchymal cell cellulose or directly upon the reactor discharge.

  • Other modifications of the hydroly­sis/physical shearing scheme will also be apparent to those skilled in the art.
  • hydrolysis coupled with physical shearing also serves to liberate parenchymal cell cellulose from parenchymal cell-containing plant material, especially sugar beet and citrus pulp. It is believed that the various forms of bonding between the parenchymal cell walls comprising parenchymal cell cellulose and other forms of cellulose in spent sugar beet pulp or other plant material is disrupted through the combination of hydrolysis and physical shearing.

  • the exit end of each reactor tube is provided with an adjustable orifice of small cross-sectional dimension.

Additionally, other solid components may be present. It is preferred that the crude parenchymal cell cellulose be bleached or otherwise rendered more suited to dispersion by contact with a bleaching medium such as hypochlorite, peroxide, or other material.
  • the bleaching step facilitates mechanical classification and subsequent isolation of substantially pure parenchymal cell cellulose from non-parenchymal cell residuum.
  • Parenchymal cell cellulose displays several unique properties.
  • a low-solid slurry of PCC such as about 0.5% to 2% by weight in water, forms a stable homogeneous suspension following high shear homogenization. It is believed that high shear partial­ly fibrillates the membrane structure causing distention and dislocation of microfibrils from the surface, thereby creating an "expanded" or "hairy” membrane assemblage of microfibrils.
  • This suspension possesses a beneficial rheology, probably due to physical entanglement and interparticle association of the platelet-like form of the fibrillated PCC thus obtained.
  • fibrillated PCC suspensions have high resting viscosities and possess thixotropic and pseudoplastic characteristics.
  • the solution rheology of a PCC dispersion is pseudoplastic and is characteristic of a hydrocolloid suspension. It is believed that the expanded microplatelet structure of PCC is responsible for the unique solution rheology of the dispersed preparation.
  • the highly hydrated platelets can be made similar in density to water and to form gravitationally stable suspensions.
  • the gross shape of hydrated PCC is that of an elongated ellipsoid although there is considerable heterogeneity of shapes.
  • the average major dimension of the isolated membrane is 20 to 100 microns with a membrane thickness of several hundred angstroms. In the moderate imposed shear range (10 to 100 s ⁇ 1), PCC viscosity behavior can be approximated by the Bingham plastic model used commonly for characterizing colloidal suspensions or the power law.
  • PCC The mild thixotropic behavior exhibited by PCC results from time dependent translational relaxation to form a gel structure or hydrodynamic alignment upon standing or mixing, respectively.
  • the platelet-like membranes are extremely durable to shear and are not affected by extremes of temperature, salts or pH.
  • PCC concentrations in excess of 2% w/w interparticle interaction begins to dominate factors influencing the solution rheology and the viscosity rapidly increases.
  • 4% w/w PCC can form a zerogel.
  • the cellulose isolated from citrus pulp is somewhat different than that obtained from the sugar beet. While citrus PCC morphology is predominantly membranous, there is considerable heterogeneity of size; the majority of the particles cannot be sprayed through a 100 mesh screen. This is in contrast to PCC from sugar beets which has a relatively uniform particle size, and, aside from the fiber fraction, is easily rinsed through a 100 mesh screen.
  • the citrus pulp cellulose is a film former like PCC and displays a similar homogenate rheology.
  • PCC has been used at very low levels to replace such higher levels of various functional components of several different food products (e.g., the oil phase/emulsifier of mayonnaise, fat in whipping cream, egg/flour in cakes, starch in cooked puddings).
  • the control recipe has been severely stressed over that of the normal recipe, e.g., by partially replacing egg white with water, by partially replacing the whipping cream fat with water, etc.: the addition of PCC has demonstrated excellent functionalities impor­tant in foods.
  • PCC has also been used to demonstrate remarkable stabilizing and texture building properties in model emulsions, meringues, and ice creams.
  • the PCC material is an excellent texture building agent and emulsion stabilizer. At equal concentration, it demonstrates higher yield and viscosity than either microcrystalline cellulose or xanthan gum. It gives excellent shear thinning, equivalent to xanthan gum, and is more thinning with increasing temperature than is xanthan. Rheological data indicate greatly superior properties to both microcrystalline cellulose and xanthan gum for texture and stabilization purposes.
  • PCC combines both the colloidal particle type of gelation characteristic of MCC with the polymeric cross-linked type of gelation characteristic of xanthan gum.
  • parenchymal cell cellulose can be added to comestibles including foods, drugs and cosmetics in varying amounts for varying purposes. In general, however, amounts of parenchymal cell cellulose between about 0.01% and about 10% by weight of the total has been found to be useful. It is more preferred that amounts of parenchymal cell cellulose between about 0.02% and about 5% by weight be included with amounts between about 0.1% and 2% being still more preferred. Persons of ordinary skill in the art will appreciate that varying amounts of PCC will be appropriate for varying functional uses.
  • an oil-in-water emulsion such as the improvement of artificial mayonnaise, ice creams, certain thixotropic condiments and the like can benefit from inclusion of from about 0.01% and about 10% of PCC by weight of the total. Even more preferred is the inclusion of from between about 0.02% and about 5% of PCC in such materials with additions between about 0.1% and about 2% by weight being still more preferred.
  • Similar considerations attend the consideration of improved water-in-oil emulsions where amounts of parenchymal cell cellulose between about 0.05% and about 20% by weight, still more preferably between about 0.1% and 10% by weight, and even more preferred between about 0.2% and 5% by weight can be used.
  • Such water-in-oil emulsions include certain condiments, spreads and the like. Pharmaceuticals and cosmetics having these kinds of emulsions benefit from similar treatments and they employ generally similar amounts of parenchymal cell cellulose for their improvement.

  • Flow curves stress as a function of shear rate were recorded with a Haake RV100 plotter from an M500 viscometer using an MV2 sensor. Shear rates from 14 sec ⁇ 1 to 160 sec ⁇ 4 were modelled with the Casson model to calculate the yield stress value. Subsequently, the power law plastic model was used to calculate the consistency coefficient (viscosity at 1 sec ⁇ 1) and flow behavior index (degree of shear thinning). The range of shear rates is characteristic of those in the mouth during chewing, Burger, Sherman, Morris and Taylor; Gums and Stabilizers , (1982).
  • Figure 1 shows yield values as a function of temperature for PCC, xanthan gum and Avicel®.
  • Figure 2 compares data for a lower concentration of xanthan gum and PCC. Particularly at temperatures associated with storage of foods and consumption of non-hot foods, PCC is dramatic in its higher yield values. This greater structure building property is important both for the shelf stability and for the desired levels of texture required for a wide variety of foods (especially impor­tant for "lite" foods where a low level of solids is wanted).
  • Products such as milk shakes, yogurts, pud­dings, juice concentrates, custards, whipped toppings, icings, jams, etc. are all indicated as candidates for incorporation of PCC to achieve added value. Improved "cling" for salad dressings is indicated in addition to enhanced emulsion stability.
  • Viscosity at 1 sec ⁇ 1 is shown as a function of temperature in Figure 4.
  • PCC is consistently more viscous (the same trends are indicated for both 1% and 0.5% concentrations) - therefore better stabilizing ability and textural enhancement via "thickening".
  • the exceptional viscous properties at low temperatures are again favorivelyable for achieving the texture wanted in those products listed above with respect to yield values.
  • Figures 6 and 7 show that PCC has shear thinning ability almost identical to xanthan gum - and the latter is the most shear thinning of presently allowable food ingredients, Morris and Taylor, Gums and Stabilizers , (1982).
  • Figure 8 indicates concentration dependence of viscosity and yield values.
  • PCC has consistently superior rheological properties to both Avicel® and xanthan gum for food texture, stabilization, and flavor release.
  • These properties - gel structures (both colloidal and polymer cross-linked), colloidal stabiliza­tion, flavor release - make possible both new products that are calorie-reduced, have improved mouthfeel, and are easier to process, and improved, cost-reduced existing products.
  • Additional data indicate that PCC has an even greater degree of polymeric cross-linking at the molecular level - the high gel modulus values, measured with a Rank shearometer, reflect gelation resulting from interactions at the molecular level which is analogous to the type of gelation that is achieved with pectin and alginates.
  • the properties indicated by this study are also achieved in emulsions, dispersions, foams, as well as in full product formulations such as puddings, salad dressings, etc.
  • a range of products will benefit by use of PCC.
  • PCC has potential for many functional applications in foods. It has properties that will make it superior to either MCC or xanthan gums, two of the "Gold Standards" of the food industry. In general, it is believed that PCC can serve to better effect than either xanthan or MCC in any application where these materials are useful.
  • PCC can also be used with positive results as a thickener in jams and other spreads; as a textural enhancer or as a partial flour replacement in breads and other cakes; as an aid for extrusion of doughs (from its shear thinning ability) and of cereals; as a stabilizer and/or as a textural enhancer for ice creams, salad dressings, etc.; as a suspension aid, stabilizer, and textural enhancer in beverages such as egg nogs, milk shakes, chocolate milk, etc.; as a thickening agent in cooked puddings and instant puddings; as a foam stabilizer in other fat based "whips", protein stabilized foams (e.g., marshmallows, artificial whipped creams, etc.), or other foams used as foods; to provide stability during storage and ease of use for such convenience com­modities as prepared cake icings, instant drinks, packaged spreads, etc.; as an aid for frozen meats and fish to avoid deterioration during storage and to

  • Example 2 Using the bleached PCC of Example 2, a series of homogenates was prepared with three commercially available carboxymethyl celluloses (CMC) obtained from Sigma Chemical Company designated low (lv), medium (mv), and high (hv) viscosity preparations. A 1% w/w solution of each CMC variety was prepared using tap water. Bleached PCC was added to each respective CMC preparation and sufficient tap water added to give final PCC and CMC concentrations of 0.75% w/w and 0.1% w/w, respectively.

  • the viscosity of each mayonnaise was measured as a function of shear rate (from 9 to 490 sec ⁇ 1) on a Bohlin Visco 88 viscometer.
  • the data were modeled with the Casson model to calculate yield stress values, and with the power law plastic to calculate the flow behavior index (FBI), and the consistency coefficient (CC), the viscosity at a shear rate of 1 sec. ⁇ 1.

  • Comparison of X and Xa indicates that increased firmness and gelation is possible also by homogenizing at a higher energy so that smaller droplets of oil are achieved. Optimization of textural and stability parameters are thus readily manipulated, by one experienced in the art, principally by increased levels of PCC and to a lesser extent by more efficient means of homogenization, for example with a Manton Gaulin.
  • a commercial mayonnaise was found to have a gel modulus of 1020 N/a2, a yield of 36,000 mPa, an FBI of 0.79, and a CC of 3700 mPa.s.
  • PCC serves three main functions in these mayon­naise recipes: (i) in replacing part of the oil phase it performs as an "active" filling agent (much lower levels of PCC being required than the amount of oil being replaced) occupying interstitial spaces between the oil droplets; (ii) protection of the oil/aqueous interface is provided by the ability of the PCC to act as an emulsifying agent and interactive component - this is demonstrated by the ability to replace part of the egg yolk which is the principal emulsifying material in mayonnaise; (iii) because of its unique ability to set up an elastic structure and to increase viscosity, the PCC gives great ability to build texture producing smoothness, creaminess, spreadability, pourability, etc. with these properties all manipulable by one experienced in the art of food emulsions and dispersions.
  • model emulsions demonstrate properties of PCC in comparison to standard hydrocolloids presently on the market.
  • these "model" emulsions suggest usefulness of PCC in salad dressings, and products of thicker texture such as spreads.

  • Model emulsion B 30% corn oil, 0.3% sodium stearoyl lactylate, water.
  • the power law plastic model was used to calculate the consistency coefficients (viscosity at 1 sec ⁇ 1) and flow behavior index (degree of shear thinning).
  • Gel moduli were measured with a Rank pulse shearometer in the variable separation mode. Aliquots of each emulsion were put into test tubes and let stand for 48 hours at which time the amount of separated aqueous phase was measured (Normal phase separation). Then each tube was centrifuged in an IEC clinical centrifuge (model CL) for 15 minutes at a setting of "7" and the percentage of separation was again measured (accelerated).
  • PCC has far superior texture building properties to most other hydrocolloids.
  • PCC gives the highest yield, the second highest viscosity, the greatest degree of shear thinning, and second highest gel modulus.
  • CMC hv gave the highest gel modulus reflecting it to be more of a solubilized molecular species and less of a colloidal particle.
  • stearoyl lactylate only xanthan gum gave higher yield and viscosity.
  • the stabilizing and textural enhancement abilities of PCC occur (i) by protection of the oil/water interface, (ii) by “actively” filling the spaces between the oil droplets, and (iii) by providing a mechanical (i.e., via enhanced viscosity and/or increased elasticity) barrier to destabilization processes.
  • PCC provides both great stabilizing ability and great textural enhancement.
  • the former is important for most dispersions and emulsions of technological importance; the latter is especially important for food applications.
  • the ability to aid in foam formation was assessed.

Then an aqueous solution containing 1/4 tsp. salt, 50 gm of sugar, and 70 ml of a 0.2% dispersion of the listed hydrocolloids - 70 ml water for the control was added. While continuing to whip the egg white, the aqueous mixture was added over about a 2 minute period. Foam density at room temperature was recorded and an aliquot was baked for 7 minutes at 425°C, in a GE Toast-R-OvenTM, model TR30B 8411.
  • foams demonstrate (i) the ability of PCC to act as a fat replacer, (ii) the ability of PCC to aid in achieving high overruns in foams, and (iii) the ability of PCC to build elastic structure required for foam stabilization, i.e., it acts as a foam stabilizer.
  • Cake 5-2 had a non-uniform dark brown color, while 5-4 was a uniform golden brown color. On cooling there was some volume reduction for both 5-2 and 5-4, with the tops of the cakes falling and leaving raised (curled) corners; separation from the pan sides was about 3-4 mm. Recipes 5-1, 5-3 and 5-5 all had a normal cake-like appearance. They were uniformly golden brown in color, with raised centers and some cracking in the middle, and no reduction in volume on cooling. The separation from the pan sides was about 1-2 mm. Removal of cakes from the pans was easy and without any tearing. Cake 5-2 was the darkest in color; 5-4 was intermediate between 5-2 and the others.

  • a third cake (recipe 5-8) was made with recipe 5-7, using 1/2 cup of 2% PCC w/w (aqueous) in place of the 1/2 cup of water.
  • Recipe 5-6 gave a uniformly golden cake that did not shrink from the sides of the pan on cooling with a texture that was soft, light and not rubbery.
  • the cake from recipe 5-7 was a darker brown and shrank away from the sides of the pan by about 3-4 mm during cooling. Its texture was hard and rubbery.
  • Recipe 5-8 looked almost the same as 5-6 with about l mm of shrinkage only at the very top of the cake. Its texture was much softer than 5-7 (slightly firmer than 5-6), and was not rubbery (very similar to 5-6).
  • Puddings were prepared using a simple starch recipe (also from R.M. Griswold). Cornstarch (36 gm) and sugar (150 gm) were mixed together and 711 ml of water was added gradually. The mixture was cooked over direct heat. It was stirred constantly until the mixture had boiled for several minutes and was almost clear. After cooling to 42 ⁇ 2°C, which required 20 minutes, a portion was poured into the cell of a Rank pulse shearometer and the gel modulus value was measured as described by S.G. Ring and G. Stainsby, "A Simple Method for Determining the Shear Modulus of Food Dispersions and Gels", J. Sci Food Agric. , 36 (1985), pp. 607-613.
  • pudding texture is not completely described by the gel modulus, this parameter does give a measure of the relative degree of gelation, particularly at the molecular level (i.e., the interacting "unit" forming the gel would be sub-microscopic in size). It is readily apparent that PCC could be used as a partial replacement for starch in such formulations. Moreover, it would function to make the preparations of such products easier where it helps to keep ingredients suspended. PCC not only helps build texture in these puddings, but it can partially replace starch, with much less PCC being required than the amount of starch removed.
  • Cake icings were prepared by creaming 1 tablespoon of margarine with 135 grams of LanticTM icing sugar and 26 ml of an aqueous phase. Five aliquots each about 20% of icing sugar and aqueous phase were creamed with a rubber spatula between each addition. Recipe 8-1 used water as the aqueous phase. Recipe 8-2 used 1% PCC in water as the aqueous phase. Both preparations were placed in a refrigerator. After four days, visual examination of the icings indicated considerable granularity in 8-1, apparently from separation of fatty globules from the aqueous phase. Icing 8-2 was smooth and creamy.
  • Ice creams were formulated using standard recipes provided with a Waring Ice Cream ParlorTM. Each recipe contained either 2 cups (formulas 1 to 10 inclusive) or 1 cup (formulas 11 to 15 inclusive) sugar, 1 1/2 tsp. vanilla extract, and 1/8 tsp. salt. Modifications were made to demonstrate the effects of PCC addition. For each recipe the ingredients were placed into the metal bucket and stirred to dissolve the sugar. Then ice was layered around the metal bucket alternately with SiftoTM pickling salt (total of 500 g salt except for recipe 7a where 300 g was used) and 2 cups of water so that the ice/salt mixture came to the top of the metal bucket. The ice and salt were layered while the metal bucket was rotated.

  • PCC PCC use in spreads was made by making 50/50 dispersions of corn oil and water with 2% PCC and 0.5% of a surfactant. For each surfactant, 1 g was dissolved (or dispersed) in 100 g corn oil. To this were added 50 g of 8% PCC (aqueous) and 50 ml water using the lowest setting ("1") on the Hamilton Beach blender. The entire mixture was then blended for 3 minutes at the highest setting ("7"). Observations were made at 1 hour and again after three days of storage in the refrigerator.

  • certain emulsifiers allow sufficient stabilization: Alkaphos L3-64A, Crodesta LS-40, Emsorb 6901, Pluradynes NP-40 and NP 100, Pluronics L35 and L122, Tween 20, and Tween 60.
  • Emulsions formed with these, but without any PCC are very runny and liquid.
  • emulsions formed with PCC had the consistency of a fairly thick mayonnaise.
  • Such formulations provide a base to which may be added other ingredients to provide a range of spreads and dips. For example, addition of Kraft dinner cheese powder provides a type of cheese spread. Variation in the level of ingredients, including the level of PCC, provides a wide range of consistencies.
  • the first mode involves electrostatic stabilization as explained by traditional DLVO theory, therefore, control of pH and ionic strength are critical.
  • stabilization normally correlates with a particular range of HLB values where the HLB values reflect the relative hydrophilic and lipophilic properties of the surfactants.
  • the second mode of stabilization involves steric stabilization; control of the molecular weight and concentration of the surfactant are more critical.
  • Steric stabilization is characteristic of polymeric materials whereas electrostatic stabilization is characteristic of small molecule surfactants.
  • Emulsifier I was added to 100 g of 8% (aqueous) PCC. This was added to 100 ml of water, or 100 ml of an aqueous solution. This aqueous mixture was then added to emulsifier II dissolved in !00 ml of corn oil, while blending at setting "1" on a Hamilton Beach blender. After complete mixing, homogenization was effected at setting "7" for 3 minutes. Of these emulsions the best was that prepared with Tween 20 and Span 80 which did not show oil separation even after 1 1/2 months.
  • the appearance of the cooked patties was similar for standard and test recipes. However, for the control samples there was congealed brown solid material in the liquid which exuded from ("cooked out" of) the patty. This congealed material was gelled protein from the lean part of the beef. The control patties were also noticeably shrunken after cooking relative to any of the other patties after cooking.
  • PCC greatly aids in preventing weight loss during the cooking of these meat patties.
  • higher levels of water are possible without the undesirable effect of losing valuable protein in the exuded liquid during cooking.
  • a bulk quantity of emulsion was prepared by grinding 4.59 kg of lean beef with 1.56 kg of pork backfat on an Urschel ComitrolTM 1700 fitted with a 3 inch cutting head of 0.030 N blade thickness and 0.060 N gap (id. No. 66774 3k03006OU). Prior to grinding, the beef and pork fat were cut into 1 inch cubes; any fat or gristle was trimmed from the beef. The material was processed through the ComitrolTM three times, with handmixing in between, to ensure reasonable homogeneity. Aliquots of this bulk material (homogenate) were then used to prepare the meat emulsions.
  • PCC material both 1% and 2% aqueous suspensions prepared from 7.43% aqueous PCC was homogenized on a Waring blender for 15 minutes and cooled to 4°C prior to preparation of the meat emulsions.
  • Meat emulsions were cooked in 2 5/16 inch diameter CorningTM 25350 centrifuge tubes from which had been cut the top part just below the tapered section. A wire mesh was fitted at the bottom of the straight side portion so that liquid could drain down into the bottom tapered part of the tube. Meat emulsion was hand stuffed into each tube to an approximate total volume of 125 ml.
  • Chicken legs were respectively dipped into (i) water, (ii) 0.2% PCC (aqueous), (iii) 0.5% PCC, and (iv) 1%PCC. After thus wetting, each was coated with Shake & Bake as per instructions accompanying that product. Two chicken legs were used for each (a total of 8 legs). These were baked at 400°F for 35 minutes and then allowed to cool to room temperature. Considerable juice had exuded from (i), less from (ii) and none from either (iii) or (iv). The juice gelatinized when cool, indicating that proteinaceous materials had been extracted from the chicken meat. The appearance of the coatings was dry for (iv), moist for (i) and intermediate for (ii) and (iii).
  • Frozen medium sized shrimp were thawed and dipped into either (i) tap water, (ii) 0.2% PCC (aqueous), (iii) 0.5% PCC, or (iv) 1% PCC. Each was then rolled in bread crumbs and cooked for 3 minutes in a deep fryer containing corn oil maintained at 355°F. After cooking, the shrimp were placed on paper towelling to absorb any excess fat. Those from both (i) and (iv) were not crisp and the coating tended to be soggy. The coatings of those from (ii) and (iii) were crispier and gave a "juicier" bite.
  • Dispersions were prepared by adding I part (wt) orange juice concentrate to 3 parts of aqueous mixtures containing (a) only water, (b) 0.13% PCC, 0.013% Methocel F50-lv, (c) 0.13% PCC, 0.013% Methocel K35-lv, (d) 0.13% PCC, 0.013% Methocel A15-lv, (e) 0.13% PCC, 0.13% Methocel E15-lv, (f) 0.13% PCC, 0.013% CMC-mv, and (g) 0.13% PCC, 0.013% Klucel.
  • dispersion was first obtained at Medium speed on a Hamilton Beach Scovil mixer for 10 minutes.
